Matrices!! My blog is better than yours.. :)

This is probably one of the easiest sections we have learned all year in Advanced Math so be ready for an AWESOME blog ;)

First we will learn to multiply matrices:

(a)(b)x(b)(c)
The inner numbers have to match, or you can simply not do it. If you even attempt your an idiot.
The answer to this matrices will be a(c).

Example 1:
Find each matrix product, if it is defined.
[-3 [-4 1 =Not Defined
1] 1 -6]
2x1 2x2
The inner numbers don't match so you cant do it! Hahaha tricked ya! :-P

Example 2:
Find each matrix product, if it is defined.
[0 1 [5 2 = [4 9
1 3] 4 1] 17 5] This is your answer! It is easy I know :)
2x2 2x2

Example 3:
Find each matrix product, if it is defined.
[1 -1 [-3 =Not Defined
2 6 -7
-5 4] 0]
3x2 3x1

Once again the inner numbers don't match so this one you can't do, so don't try.
